California Contractor Insurance Requirements by Trade

California requires every licensed contractor to carry a $25,000 license bond and workers' compensation insurance (or file an exemption when eligible). LLC licensees must also carry liability insurance. Requirements vary with license status, employees, classification, and business structure; an exemption is not available to every trade.

These guides explain the insurance requirements and risk profile for each major California contractor trade. Each page covers what the CSLB requires, what it does not, and what additional coverage you should verify before hiring.

Common Requirements Across All Trades

Regardless of trade, every active California contractor must maintain:

  1. Contractor license bond ($25,000) filed with the CSLB. Protects consumers against violations of the Contractors State License Law.
  2. Workers' compensation insurance if the contractor has any employees. Sole proprietors with no employees may file an exemption only if their classification and circumstances qualify under current CSLB rules.

CSLB requires liability insurance for LLC licensees. Other contractors may need it under their project contracts. Ask about policy limits, exclusions, and proof of coverage before work begins.
